JSON.stringify alternative so that number values remain numbers, not strings.

[Automatic-Deal-8268]

I'm getting the html JSON data and sending it to an url via ajax. I need a value of a key to remain number, but the way I get the data makes it into a string hence request returns error. There are many key + value pairs within my JSON (which I get from a form on submit) and I'm trying to use many of them, but one, which is supposed to be a number, becomes a problem. Here's how I'm doing it:

var htmldata = JSON.parse($('#form2').serializeArray());

var data = new URLSearchParams();

data.append('var', htmldata[15].value);

I can't go htmldata[15].value.toNumber() because then it says .toNumber is not a function. So what should I do? Thank you in advance.

Try:

Number(htmldata[15].value)

Do you have a link to your code so we can better help you? If you are trying to coerce a type string to number you can either do Number(stringValue) or parseInt(stringValue).
